Horry County officers were called there that day in regards to a cardiac arrest. Horry County Fire Rescue got to the home first and found 25-year-old Porscha Cobb dead inside, according to authorities.

As police swept through the home, they found her brother, 26-year-old Dexter Cobb, dead.

Authorities previously said the pair were brother and sister.

The two were shot, according to an arrest warrant, which also states “It was found the two victims had both suffered gunshot wounds while inside the residence. During the course of the investigation a credible witness did state the defendant had admitted to them he’d killed the victims and did provide details unknown to the public.”

Gore is being held at the J. Reuben Long Detention Center, and is awaiting an initial appearance on the charges.
